Species ecology can be influenced by different factors at different scales. There are three approaches about the ecological differences between species: the first brings that differences result from current processes on niche characteristics (e.g. diet, time, space); the second that species differences are explained by random patterns of speciation, extinction and dispersion, the third that historical events explain the formation and composition of species in communities. This study aims to evaluate the influence of phylogenetic relationships in determining ecological characteristics in amphibians (globally) and test with that, if ecological differences between species of frogs are the result of ancient pre-existing differences or as result of current interactions. Another objective of this study is to verify if ecological, historical or current characteristics determine the size of species geographical distribution. The diet data for analysis of trophic ecology were collected from published literature. We performed a non-parametric MANOVA to test the existence of phylogenetic effects in diet shifts on frogs history. Thus, it is expected to know the main factors that allow the coexistence of anuran species. We performed a phylogenetic regression to analyze if niche breadth, body size and evolutionary age variables determine the size of the geographical distribution of amphibians in the Amazon. In the present study, new contributions to knowledge of major ecological patterns of anurans are discussed under a phylogenetic perspective / Entender a origem, manuten??o e os mecanismos que operam na biodiversidade atual s?o um dos principais objetivos da Ecologia. A ecologia das esp?cies pode ser influenciada por diferentes fatores em diferentes escalas. Existem tr?s abordagens a cerca das diferen?as ecol?gicas entre as esp?cies: a primeira traz essas diferen?as resultam de processos atuais atuando sobre as caracter?sticas do nicho (dieta, tempo, espa?o, etc); a segunda que diverg?ncias no nicho das esp?cies s?o explicadas por padr?es rand?micos de especia??o, dispers?o e extin??o; a terceira que eventos hist?ricos explicam a forma??o e a composi??o das esp?cies nas comunidades. Este estudo tem como objetivo avaliar a influ?ncia das rela??es filogen?ticas na determina??o de caracter?sticas ecol?gicas em anf?bios (globalmente) e testar, com isso, se as diferen?as ecol?gicas entre as esp?cies de anuros s?o resultado de diferen?as antigas pr?-existentes ou como o resultado de intera??es ecol?gicas mais recentes. Outro objetivo deste estudo ? verificar que caracter?sticas ecol?gicas, hist?ricas ou atuais, determinam e influenciam o tamanho da distribui??o geogr?fica das esp?cies. Os dados de dieta para a an?lise da ecologia tr?fica dos anf?bios foram coletados a partir da literatura j? publicada. Realizamos uma MANOVA n?o param?trica para testar a exist?ncia de efeitos filogen?ticos nas principais diverg?ncias na dieta dos anuros. Com isso, espera-se conhecer os principais fatores que permitem a coexist?ncia das esp?cies de anf?bios anuros e quais os principais n?s da filogenia de anf?bios respons?veis pelas diferen?as observadas atualmente no nicho tr?fico das esp?cies. Realizamos uma regress?o filogen?tica para analisar se as vari?veis de largura de nicho, tamanho corporal e tempo de diverg?ncia determinam o tamanho da distribui??o geogr?fica dos anf?bios anuros da Amaz?nia. Neste trabalho, novas contribui??es ao conhecimento dos padr?es ecol?gicos apresentados pelos anuros s?o fornecidas e discutidas sob uma perspectiva filogen?tica

With the goal of avoiding and reducing the accident risks with oil it is necessary to understand the natural vulnerability, mapping natural resources and monitoring the oil spill. The use of computational tools for environmental monitoring makes possible better analyses and decisions in political management of environmental preservation. This work shows a methodology for monitoring of environment impacts, with purpose of avoiding and preserving the sensible areas in oil contact.
